asCID()

static asCID<Data, Format, Alg, Version, U>(input): null | CID<Data, Format, Alg, Version>

Takes any input value and returns a CID instance if it was a CID otherwise returns null. If value is instanceof CID it will return value back. If value is not instance of this CID class, but is compatible CID it will return new instance of this CID class. Otherwise returns null.

This allows two different incompatible versions of CID library to co-exist and interop as long as binary interface is compatible.

Type Parameters

Type Parameter

Data

Format extends number

Alg extends number

Version extends Version

decode()

static decode<Data, Code, Alg, Version>(bytes): CID<Data, Code, Alg, Version>

Decoded a CID from its binary representation. The byte array must contain only the CID with no additional bytes.

An error will be thrown if the bytes provided do not contain a valid binary representation of a CID.

Type Parameters

Type Parameter

Data

Code extends number

Alg extends number

Version extends Version

Parameters

Parameter

Type

bytes

ByteView<Link<Data, Code, Alg, Version>>

Returns

CID<Data, Code, Alg, Version>

Defined in

node_modules/multiformats/dist/src/cid.d.ts:70

decodeFirst()

static decodeFirst<T, C, A, V>(bytes): [CID<T, C, A, V>, Uint8Array]

Decoded a CID from its binary representation at the beginning of a byte array.

Returns an array with the first element containing the CID and the second element containing the remainder of the original byte array. The remainder will be a zero-length byte array if the provided bytes only contained a binary CID representation.

Type Parameters

Type Parameter

T

C extends number

A extends number

V extends Version

Parameters

Parameter

Type

bytes

ByteView<Link<T, C, A, V>>

Returns

[CID<T, C, A, V>, Uint8Array]

Defined in

node_modules/multiformats/dist/src/cid.d.ts:80

inspectBytes()

static inspectBytes<T, C, A, V>(initialBytes): object

Inspect the initial bytes of a CID to determine its properties.

Involves decoding up to 4 varints. Typically this will require only 4 to 6 bytes but for larger multicodec code values and larger multihash digest lengths these varints can be quite large. It is recommended that at least 10 bytes be made available in the initialBytes argument for a complete inspection.

Type Parameters

Type Parameter

T

C extends number

A extends number

V extends Version

parse()

static parse<Prefix, Data, Code, Alg, Version>(source, base?): CID<Data, Code, Alg, Version>
